Locomotive, Diesel, GE U50

History: The GE U50 was an eight-axle, in B-B-B-B configuration, 5,000 hp (3,700 kW) road switcher diesel-electric locomotive built by General Electric. They were twin-engined locomotives, combining two 2,500 hp (1,900 kW) diesel engines.
The U50 was built in response to the Union Pacific Railroad's requirement, issued in the early 1960s, for a 15,000 hp (11,200 kW) 3-unit locomotive intended to replace the turbines. The design was effectively two U25B locomotives on a single frame; each diesel engine and generator powered only the two trucks at the same end.
26 U50 have been produced, 23 for UP and 3 for SP. They were all scrapped by 1977.
